Product Description BEFORE PURCHASING, check to see if the Wi-Fi thermostat you will pair with this adapter is compatible with your home and determine if your home needs a C-wire power adapter. The C-wire adapter should work for all applications in which the thermostat being replaced doesn't have a common wire and does have Y and G wires attached. The C-Wire Power Adapter makes Honeywell Home smart thermostats compatible with most homes that don?t have a common wire. Quickly and easily power connected thermostats that require a c-wire. Use for Wi-Fi, 24v Honeywell Home thermostats when a common wire is needed but not present. Note, your home may have an unused C-Wire that should be verified before purchasing this adapter. Easy push terminals and an adhesive mount make installation quick and easy. Simple adhesive mount allows you to attach the adapter to the outside of your furnace. Be discreet with a closed cover to conceal internal components and wires. The sleek, modern Honeywell Home exterior keeps the installation site clean and professional. COMPATIBLE WITH: Forced air (gas, oil or electric), hot water and steam, and heat pumps with electric backup. Does NOT work with electric baseboard heat (120-240V). NOTE: The C-Wire Adapter will work with multi-stage systems including heat pumps if your Wi-Fi thermostat will work with these systems; however, please follow the installation directions carefully to avoid disconnecting incorrect wires.
